We recently published a list of Billionaire Stephen Mandel’s 10 Stocks with Huge Upside Potential. In this article, we are going to take a look at where Flutter Entertainment plc (NYSE:FLUT) stands against other billionaire Stephen Mandel’s stocks with huge upside potential.

With economic policy and trade tensions fueling volatility, investors are moving through one of the most unpredictable markets in recent times. The Federal Reserve has taken a wait-and-see stand and maintains elevated interest rates to control inflation. In a CNBC report, the Fed commented that a rate cut could happen as early as June if economic conditions declined further. Such monetary easing would make the stock prices go up, with some companies even outperforming their peers in the market.

The possibility of falling rates is a big deal for investors. Lower interest rates have often led to higher equity valuations, making borrowing cheaper and compressing discount rates applied to future earnings. Various stocks, irrespective of their sector, have historically shown strong rebounds during previous periods of rate cuts. Seasoned investors like billionaire Chase Coleman have also observed similar patterns. Leading the charge among them is growth stocks.

In addition to the renewed trade conflicts under President Trump’s tariff policies, the looming uncertainties are thickening with inflation getting closer to the Federal Reserve’s 2% target. Under these circumstances, having understood the potential of a confirmed pivot from the Fed on loosening the monetary policy, the investors are keeping a close watch on their moves since it would also inevitably benefit stocks with substantial upside potential.

But isn’t betting on short-term moves risky? Of course, it is. However, as reported on CNBC, the market indices suffered a sharp 12% correction earlier this month but staged a quick comeback. Those who panicked and sold at the lows are now regretting their decisions. This episode raises the importance of maintaining discipline and a long-term view when making investment decisions.

Setting aside the turbulence, historical data could be used to understand the importance of equities in wealth accumulation. Between 1926 and 2024, the U.S. stocks surpassed the Treasury bills by providing an annual return of 10.2%, which exceeded the Treasury’s 3.3%. To benefit from such an edge, the investors must endure through volatility and understand that 10% to 20% declines are part of the game.

In this economic landscape, investors should follow the billionaire investors. Using their knowledge about the market and companies and by conducting extensive research, some billionaire investors like Andreas Halvorsen have made investment decisions, stuck to them, and benefited immensely. Similarly, with his strategically positioned portfolios, one of the most prominent billionaire investors, philanthropists, and the founder of Lone Pine Capital, Stephen Mandel, guides other investors to capture outsized returns without reacting impulsively to market noise.
