What's better than owning an S&P 500 stock that's up big over the past six months? One likely to jump in the future.

Welcome back Palantir Technologies[ticker symb=PLTR]. It's again the top stock in the S&P 500 so far this year — thanks to a stellar April.

The S&P 500 rallied back in May, undoing a third monthly drop in April. And it marked a big month of gains for some stocks.

Don't be tempted by the hundreds of new ETFs that launch every year. Very few are deserving of a spot in your portfolio, says Morningstar.

Curious which S&P 500 stocks investors think are worth a premium? Just look at the ones with the highest valuations.

Everyone has told you selling S&P 500 stocks out of fear will cost you — but how much? Try $7.6 trillion in just about a month.

A new bull market for the Nasdaq has kicked off — and some S&P 500 stocks are already taking off faster than the rest of the market.

Investors worry many S&P 500 companies will pay the price with lost growth from tariffs. But analysts think some will grow despite them.

Just a month ago, ETF investors were pleased to simply hold onto their money. Now they're looking for big gains in the S&P 500 again.

Savvy investors know that buying leading growth stocks is the best way to profit long term. But there's a rush to buy the dip in the S&P 500.
