And then there were two. After 10 grueling trading days and five rounds of action in TheStreet's Market Bracket Challenge, we have tech heavyweights Facebook(FB) - Get Report  and Apple(AAPL) - Get Report left in our bracket.

The field was whittled to four stocks earlier in the week, but Illumina(ILMN) - Get Report and Nike(NKE) - Get Report just weren't able to pull off victories again. 

So now, its Zuckerberg and Cook. Funny enough, Menlo Park and Cupertino, Calif. are about 14 miles apart. Perhaps the two can meet at Alphabet's(GOOGL) - Get Report Googleplex, which is roughly halfway between the campuses, and watch the final matchup.

But before we look ahead to the exciting, one-day matchup of Apple vs. Facebook that will take place on Monday, let's take a look back at the Round of 4, which took place from Thursday to Friday.

Here are the highlights: 

Apple Kicks Nike to the Curb 

It was never really a contest, to be honest. After taking a bit of a hit yesterday, the Beaverton, Ore., footwear maker continued its decline on Friday. Apple, meanwhile managed to stave off a big dip over the past two days, finishing down less than 1% over Thursday and Friday. Maybe it was just a lack of real catalysts for Nike, or maybe it was the fact that Under Armour(UA) - Get Report recently released a high-end sneaker (priced at $300 per pair) that could challenge Phil Knight's apparel powerhouse. 

On the Apple front, analysts seemed bullish on the Cupertino, Calif., tech company, and that was enough to keep its stock from dipping too much and putting it out of the running. Canaccord Genuity analyst Mike Walkley on Friday reiterated his buy rating on Apple's stock and hiked his price target to $165 from $154, saying the company has "little to fear" from Samsung's new Galaxy S8. And then there was that talk earlier in the week that the company could be worth as much as $200 per share in the not-so-distant future.

Illumina Can't Keep Its Winning Sequence Going

Oh, Illumina. You plucky, $25.1 billion in market cap, gene sequencing company, you. The South Carolina of TheStreet's Market Bracket Challenge, Illumina had its title hopes dashed late this week as the company posted a 0.8% dip over the past two days. Illumina couldn't muster the gains it needed to topple the House that Zuck Built, which only ticked down about quarter of a percentage point. 

Zuckerberg's social media behemoth posted a slight loss over the past two trading days, enough to eke out a victory and punch its ticket to the title matchup. Facebook investors shrugged off news that Palmer Luckey, co-founder of Facebook's virtual reality company, Oculus, would be leaving the company. The dominant themes for Facebook over the past week or so (and going forward for that matter) continue to be how it plans to eat Snap's (SNAP) - Get Report lunch and how digital ads and marketing will continue to proliferate on the internet. Investors shrugged off news of a congressional ruling that could make it easier for cable operators and telecoms to sell patrons' personal data for profit.
