Turns out that Warren Buffett made a bet on Apple stock years ago that turned into a whopping $120 billion dollar win. According to CNBC:, this one of Buffett's biggest wins in history: Warren Buffett’s out-of-character bet on Apple may end up being one of his winningest investments, making more than $120 billion on paper as the tech giant shattered yet another record to top a $3 trillion market valuation this week. Berkshire Hathaway began buying Apple stock in 2016 and by mid-2018, the conglomerate accumulated 5% ownership of the iPhone maker, a stake that cost $36 billion. Flash forward to 2022 and the Apple investment is now worth $160 billion as the massive rally extended into the new year.
