Amid global growth concerns, looming Brexit issues and an unresolved trade spat with China, the U.S. market bulls are still raging. This is especially true as better-than-expected earnings have renewed confidence in the stock market. Upbeat results from Twitter Inc , Coca-Cola Co (KO Quick QuoteKO - Free Report) , United Technologies Corp and Lockheed Martin Corp (LMT Quick QuoteLMT - Free Report) eased fears of a profit recession.

Notably, the S&P 500 Index and the Nasdaq Composite hit new all-time record closings on Apr 23. With this, the S&P 500 climbed nearly 25% from a low reached on Christmas Eve while Nasdaq is up more than 30% (read: : A Spread of Top-Ranked ETFs That Crushed the Market in Q1).

Additionally, investors are feeling optimistic about the global economy given signs of improving growth in China with new measures and reforms, as well as steady albeit slowing growth in the U.S. economy. The Fed’s decision of not raising interest rates this year after seven hikes over the past two years also bolstered investors’ sentiment. Further, an oil price surge and bouts of upbeat data globally are providing strong support to the bulls.

While every corner of the market is enjoying the ascent, high-beta stocks and ETFs are outperforming.

Why?

Beta measures the price volatility of stocks or funds relative to the overall market. It has a direct relationship to market movements. A beta of more than 1 indicates that the price tends to move higher than the broader market and is extremely volatile while a beta of less than 1 indicates that the price of the stock or fund is less volatile than the market.

That said, high-beta stocks seek to capitalize on continued growth with market-beating returns. This is because when markets soar, high-beta stocks experience larger gains than the broader market counterparts and thus, outpace their rivals. However, these exhibit a higher level of volatility.

Given the bullishness, investors could find the following ETFs and stocks intriguing:
