Apple (AAPL +1.63%) suffered its worst one-day stock fall in over a year yesterday, after the iPhone maker announced price increases – on just about everything except iPhones, for now. The soaring competition for memory chips in short supply was highlighted by Micron's (MU -0.27%) exceptional results yesterday. Apple's new pricing follows Microsoft's (MSFT +1.68%) Xbox price jumps.

• "Micron's huge AI windfall is bad news for most of us": Bloomberg's Chris Bryant noted the huge memory demand from AI superscalers is likely to keep prices high until at least 2028, due to the long time it takes to get new chip factories running.
• Global tech stock sell-off: Asian markets fell this morning following the week's AI-led jitters, with South Korea's Kospi index plunging more than 8% in early trading while Japan's Nikkei lost 5%. The Nasdaq has fallen 4.4% so far this week – with futures down more than 1% this morning, while S&P 500 futures dipped 0.3%.

2. Why I'd Rather Call Market Drops "Opportunities"

By Jim Gillies

I recently passed the 30th anniversary of the date that I purchased my first stock (I was not raised in a house that knew anything about investing or owned stocks of any kind). In the three decades since I've (we've all) seen a LOT ... And through it all, the market is "up and to the right."

Investing is such a rewarding effort and, three decades into this adventure (and hoping for another three to four decades beyond today), I've personally seen and so benefited from the magic of compounding.

I thus find it rather difficult to get worked up about market drops. Indeed, at this point it's engrained in me to consider sell-offs as just another opportunity. After all, what do you think "long-term investment time horizon" means?
