NEW YORK (TheStreet) -- Deal activity in 2015 is stacking up to be even more robust than 2014.

So far this year, close to 2,300 deals have been announced with a total value of roughly $319.4 billion, according to data from Dealogic. While the number of deals is on pace with 2014, total year-to-date deal value is slightly higher than last year's $313 billion, the data says.

U.S. merger and acquisition activity set a record year in 2014, topping out at $1.62 trillion, according to Dealogic. So far, 2015 deal activity is setting up to outpace that. Notable takeover activity announced so far this year includes: Simon Property's (SPG) plans to acquire all of Macerich (MAC) for $22 billion; AbbVie's (ABBVplanned acquisition of Pharmacyclics (PCYC) for $21 billion, announced earlier this month; Staples' (SPLS) plans to acquire its competitor Office Depot (ODP) for $6.9 billion, Dealogic says.

The market for takeovers is going through "a boom that I think is going to continue through next year because the circumstances are so fertile," TheStreet's Jim Cramer told participants at December's The Deal Economy: Predictions & Perspectives for 2015 in New York City, according to prepared comments. Cramer had identified 19 companies he thought could be bought or broken up in 2015.

Cramer cited "anemic" worldwide growth, a growing trend of hedge fund activism and the fact that "deals work." For many companies, it's "much better to consolidate and create oligopolies that generate superior returns or split up and create laser focused management teams that bring out pure play value," than to try to grow organically, he said in his prepared comments.

How can ordinary investors benefit? Given that most takeovers occur at premium to the stock price, owning stock in a likely merger or acquisition candidate can result in a tidy profit once the transaction occurs.

So far none of Cramer's takeover picks have been acquired, but we've still got nine months to go this year. Check out his list.


1. Yelp (YELP - Get Report)

With its war chest of $10 billion, made up mostly of $6 billion from its sale of Alibaba shares, Cramer believes Yahoo! (YHOO) should acquire online reviews site Yelp along with several other digital businesses in order to "cobble together...an online yellow pages." The company has a market cap of just under $4 billion. Accounting for a 25% premium, Yahoo! could acquire Yelp with $5 billion to spare for other moves.

Cramer says that Yahoo! should also look at food site Grubhub, vacation rentals listings site HomeAway, hotel reviews site Trip Advisor and real estate listings site Zillow. In addition, Cramer says that Yahoo! should consider acquiring Twitter.


Grubhub (GRUB - Get Report)

Online menu and food ordering business Grubhub's market cap of nearly $3 billion means that at a 25% premium, acquiring the company would cost Yahoo! nearly $4 billion from its $10 billion war chest, made up mostly of $6 billion from its sale of Alibaba shares. Grubhub, along with several other digital businesses, would help Yahoo! "cobble together...an online yellow pages," according to Cramer.

HomeAway (AWAY)

Cramer believes that Yahoo! should acquire vacation rentals listings site HomeAway. With a market cap of $3 billion, acquiring HomeAway at a 25% premium would cost Yahoo! nearly $4 billion, less than half of the $10 billion Yahoo! has to make such moves, made up mostly of $6 billion from its sale of Alibaba shares. HomeAway could be a part of "an online yellow pages" that Yahoo! could "cobble together," according to Cramer.

Cramer believes Yahoo! should also look at food site Grubhub, online reviews site Yelp, hotel reviews site Trip Advisor and real estate listings site Zillow. In addition, Cramer says that Yahoo! should consider acquiring Twitter.


TripAdvisor (TRIP - Get Report)

Yahoo! should acquire hotel reviews site TripAdvisor, according to Cramer. With a market cap of nearly $11 billion, acquiring TripAdvisor at a 25% premium would cost Yahoo! more than $13 billion.

"I think every one of those companies is for sale. Every one. Which would I do? That's simple: I would buy Twitter," Cramer says.


Hain Celestial (HAIN - Get Report)

Cramer thinks that one of the consumer packaged goods companies -- General Mills (GIS - Get Report) , Kellogg (K - Get Report) , Campbell Soup (CPB - Get Report) , Nestle, Kraft Foods (KRFT) or Mondelez (MDLZ - Get Report)  -- should snap up organic and natural foods maker Hain Celestial. With a market cap of $5.7 billion, acquiring Hain Celestial at a 25% premium would cost approximately $7.1 billion.

Cramer believes these companies should also consider acquiring WhiteWave Foods, a maker of plant-based foods, beverages, coffee creamers, dairy and other organic products.


WhiteWave Foods (WWAV)

Cramer thinks that one of the consumer packaged goods companies -- General Mills, Kellogg, Campbell Soup, Nestle, Kraft Foods or Mondelez -- should snap up WhiteWave Foods, a maker of plant-based foods, beverages, coffee creamers, dairy and other organic products. With a market cap of $6.1 billion, acquiring WhiteWave at a 25% premium would cost approximately $7.6 billion.

Cramer believes these companies should also consider acquiring organic and natural foods maker Hain Celestial.


Monster Beverage
(MNST - Get Report)

Coca-Cola (KO - Get Report) should acquire the rest of Monster Beverage. Coca-Cola purchased a 16.7% stake in the energy drink manufacturer for about $2.15 billion in August. Monster Beverage's market cap is just about $18 billion.

Cramer also thinks Coca-Cola should buy out the remaining shares it doesn't own of Keurig Green Mountain (GMCR) .

Coca-Cola "has a fantastic balance sheet and both deals would be done with very cheap borrowed money," Cramer said. "With Monster, Coca-Cola can dominate the only beverage category with double-digit growth."


Keurig Green Mountain (GMCR)

Coca-Cola should acquire the rest of Keurig Green Mountain that it doesn't already own. Coca-Cola owns a 16% stake in Keurig Green Mountain. Keurig Green Mountain's market cap is just about $22 billion.

Cramer also thinks Coca-Cola should buy out the remaining shares it doesn't own of Monster Beverage.

Coca-Cola "has a fantastic balance sheet and both deals would be done with very cheap borrowed money," Cramer said. "With Keurig it can own the hot and cold in-home do-it-yourself beverage company to fend off homemade cola makers."


Lululemon (LULU - Get Report)

Cramer believes that Nike (NKE - Get Report) or VF Corp. (VFC - Get Report) should acquire yoga apparel maker Lululemon. Lululemon's market cap is around $6.5 billion. Cramer said both companies could afford to pay around $65 a share "without much of a problem." (The stock is currently trading at around $45 a share, meaning a $65 acquisition would be giving shareholders a 41% premium.) 


Skechers USA
(SKX - Get Report)

Cramer believes VF Corp. should acquire casual footwear and sneaker brand Skechers. Skechers' market cap is $3.1 billion. 

Skechers "would be a terrific companion to VF's Vans line of sneakers and Timberland boots," Cramer said. "While Skechers, a $3 billion company, has already appreciated 77% for the year, it has a ridiculously low 20 P/E ... 20% growth and almost no debt. It does have the fastest growing casual shoe out there and that would fill a crucial hole in VF's line-up."


Agios Pharmaceutical
(AGIO - Get Report)

Could Agios Pharmaceutical have a cure for cancer? It's a very real possibility for the the developmental-stage company with two cancer metabolism drugs in mid-stage clinical trials, according to Cramer, who thinks Celgene (CELG - Get Report) will take a "15% stake" in it this year. Celgene will eventually "take that stake to its ultimate measure, a 100% takeout maybe for as much as double where this stock is, even as it is up already 300% this year," he said.

Agios Pharma's market cap is $3.5 billion. Its stock was most recently trading at about $103. 


VeriFone (PAY)

VeriFone, the point-of-sale tech company, could be a "perfect merger partner" for ATM-manufacturer NCR (NCR - Get Report) , Cramer believes. VeriFone has a market cap of $4.9 billion. NCR has a roughly equal market cap.

"Given how much technology it [VeriFone] has, it's a natural candidate to be acquired," Cramer said. "Together the two could offer a one-stop solution for all retailers worldwide making the transition to Apple (AAPL) pay."


Blackhawk Network (HAWK)

Prepaid card leader Blackhawk is "ripe" to be bought by Alliance Data Systems (ADS - Get Report) , a provider of private label credit card loyalty programs and data-driven marketing services. Blackhawk's market cap is $1.9 billion. 


CST Brands (CST)

Cramer believes Marathon Petroleum (MPC - Get Report) should acquire CST Brands, a retailer of fuel and convenience merchandise in the U.S. CST's market cap is approximately $3.4 billion. 


Boardwalk Pipeline Partners (BWP)

A natural fit for Kinder Morgan (KMI - Get Report) would be the acquisition of energy company Boardwalk Pipeline, according to Cramer. Boardwalk Pipeline's market cap is $4 billion. 


Jack in the Box (JACK - Get Report)

It's possible that fast-food chain Jack in the Box could spin off its Mexican concept Qdoba, which competes with the likes of Chipotle Mexican Grill (CMG - Get Report) . Jack in the Box's market cap is $3 billion. A Qdoba spin off would "bring out value that's currently hidden by the hamburger business," Cramer said.


Fiesta Restaurant Group
(FRGI - Get Report)

Fiesta Group, with its "highly profitable" Pollo Tropical unit could get snapped up by Darden Restaurants (DRI - Get Report) , according to Cramer. Fiesta has a market cap of $1.5 billion.
