This market may be fickle, but it still obeys the laws of supply and demand, Jim Cramer reminded his Mad Money viewers Thursday. That's why you should never buy on day one of a selloff, as there will always be better opportunities ahead.

What sectors were in demand today? Cramer said investors are clamoring for tech. That's why the Micron Technologies (MU) secondary, originally planned to be $1 billion was increased to $1.2 billion. Even the selling in Twitter (TWTR) and Snap (SNAP) appears to be waning.

Then there are the transports, another sector in high demand, being led my FedEx (FDX) and the airlines.

Where is the supply coming from? Cramer said retail continues to ratchet lower, with J.Jill (JILL) being the latest victim, with shares plummeting 51% in a single day. Cramer noted that Ulta Beauty (ULTA) is now $125 off of its former highs.

Oil is another sector with too much supply, as prices continue to struggle to top $50 a barrel.

Finally, Cramer called out the banks, where even JPMorgan Chase's (JPM) strong earnings were not strong enough to buoy the stock. Cramer said he'd wait until at least next week before beginning to buy into any of the banks.

Executive Decision: Domino's

For his "Executive Decision" segment, Cramer checked in with Patrick Doyle, president and CEO of Domino's Pizza (DPZ) , which just posted a four-cent-a-share earnings beat on strong same-store sales, only to see its shares fall 3.9% by the close.

Doyle said that Domino's international sales are back in the 3% to 6% growth range and domestic was even better, coming in with 8.5% same-store sales growth. If you look at store sales going back three years, known as "the stack," Doyle noted that they've delivered 31% growth, and with this quarter that number is now almost 40%.

Doyle said voice ordering technology, which Domino's began investing in four years ago, is only now becoming mainstream. Domino's has also partnered with Ford (F) and is looking into new ways to deliver their products.

When asked about his company's stock repurchase program, Doyle said the company has about $250 million left of its current authorization and will continue to buy back shares. Shares of Domino's are currently up 26% for the year. 

Auto Parts Winner

One of the beauties of this bull market has been its broad base of winners, Cramer told viewers. With so many companies doing well, there are always a few that fly under the radar, making them excellent opportunities.

One of those winners is LKQ (LKQ) , a company you probably have never heard of. It is one of the leaders in specialty and after-market auto parts that has virtually no coverage on Wall Street, but has shares that are up 33% from their April lows.

After a string of disappointing quarters and the retirement of its CEO, LKQ finally got its groove back earlier this spring and is seeing the fruits of its 200 acquisitions since 1998 finally start paying off. The company invested heavily in Europe and is now that continent's largest auto part supplier, just as Europe's recovery is taking hold.

LKQ also delivered two beat-and-raise quarters in a row, and is benefiting from the increased need for auto parts after the recent hurricanes. Shares still sell for an attractive 17 times earnings. Cramer called this stock a winner.

No Huddle Offense

In his "No Huddle Offense" segment, Cramer said he's curious to see if the the board at Procter & Gamble (PG) has learned anything from their proxy fight with activist investor Nelson Peltz. Procter may have won the battle, he said, but it should serve as a wakeup call that almost half of all shareholders are not pleased with the company's performance.

There are only three winners in the consumer packaged good space, Cramer said, and they're Estee Lauder (EL) , Clorox (CLX) and Unilever (UL) . What do all three of these companies have in common? They're all innovators and they're all run by former Procter executives.

Cramer said he doesn't know how Procter was able to let these terrific and innovative individuals slip away, but the market has clearly seen what these outsiders have done for their respective companies.

Lightning Round

In the Lightning Round, Cramer was bullish on Bristol-Myers Squibb (BMY) , Eli Lilly (LLY) , Mazor Robotics (MZOR) , ZAGG (ZAGG) and McCormick (MKC) .

Cramer was bearish on Himax Technologies (HIMX) and Iridium Communications (IRDM) . 

Am I Diversified?

In the "Am I Diversified" segment, Cramer spoke with callers and responded to tweets sent via Twitter to @JimCramer to see if investors' portfolios have what it takes for today's markets. The first portfolio included Johnson & Johnson (JNJ) , Main Street Capital (MAIN) , Ship Finance (SFL) , Vectren (VVC) and DTE Energy (DTE) .

Cramer said he wasn't a fan of this portfolio and would keep only Johnson and DTE. He advised replacing the rest with United Technologies (UTX) , Waste Management (WM) and Pepsico (PEP) .

The second portfolio's top holdings included Cheniere Energy (LNG) , Clovis Oncology (CLVS) , Kratos (KTOS) , Enterprise Products Partners (EPD) and Halozyme (HALO) .

Cramer suggested replacing Halozyme with United Technologies to be properly diversified.
