In this article, we will discuss the 12 Best Multibagger Stocks to Invest In According to Billionaires.

On March 11, Tom Lee of Fundstrat joined ‘Closing Bell’ on CNBC to discuss his market outlook amid rising oil prices and sector volatility. Lee acknowledged his contrarian stance and maintained a base case that the market will eventually experience a 20% decline, or a bear market, later this year. However, he clarified that such a decline typically occurs when the market stops responding to good news. For the immediate term, he believes that the speculation has already been flushed out of software, the Mag 7, and cryptocurrency. Consequently, he bets that markets will lift through the end of March and potentially reach a level of 7,300 before a bear market shows itself later in the year.

Regarding the technology sector, Lee believes that software has already bottomed. He explains that negative risks have been priced in and multiples have contracted significantly. The IGV software ETF index has lost five multiple points and now trades at a forward P/E ratio of 16 times. Lee viewed this as a cyclical valuation for a universe of 110 stocks that mostly possess durable businesses, making it an attractive entry point. He noted, however, that if growth stocks outperform as he expects, it may not necessarily support a broadening trade across the wider economy, as the stock market and the economy do not always move in tandem.
