After nuking fears that the iPhone X may be a colossal failure somehow, Apple’s stock price has been on a climb this week with AAPL touching a new high during intraday trading. As CNBC notes, investors responded positively to Warren Buffett’s Berkshire Hathaway firm upping its investment in Apple by 75 million shares last quarter. Apple CEO Tim Cook has responded to the news of Berkshire’s investment:

Buffett described Apple as an ‘unbelievable company’ that ‘earns almost twice as much as the second most profitable company’ in the US, and Buffett’s faith in Apple helped push the stock price up to $183.65 per share. Peak AAPL performance is also helping the Dow Jones Industrial average tick up 220 points today, per CNBC:

AAPL’s climb also follows a week that began with analysts predicting poor iPhone performance during the company’s last quarter. Apple did report flat growth in iPhone unit sales, but increased iPhone revenue pleased investors and shows the higher-priced iPhone X is performing well.

The S&P 500 rose 0.75 percent after falling 0.4 percent, buoyed by a 1.3 percent gain in technology stocks. The Nasdaq composite rose 1.2 percent thanks to the aforementioned rally in Apple, a 1.3 percent gain in Facebook and a 1.2 percent boost in Google-parent Alphabet.

The company also called out the iPhone X as the most popular model in the product lineup which is a new trend; higher-priced Plus models of iPhones were never more popular than slightly cheaper and smaller flagships in previous years.
