After a volatile January, Wall Street has been showing strong momentum this week with the S&P 500 and the tech-heavy Nasdaq Composite Index scaling new highs.Solid corporate earnings and expectations of a large stimulus by U.S. President Joe Biden’s administration have rekindled the appeal for the riskier assets. The stronger-than-expected results so far in the fourth quarter have led analysts’ to raise their estimates for the coming quarters. Earnings growth for Q4 has turned modestly positive, following three-straight quarters of decline, thanks to impressive results from the tech sector leaders.Additionally, signs of a healing labor market, continued optimism surrounding new vaccines, widening reach of vaccination, and easing restrictions are also driving the stock higher (read: 6 Hot ETFs That Could be Investors' Darling in February). While every corner of the market is enjoying this ascent, high-beta ETFs and stocks seem a perfect bet at present.Why High Beta?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 the stock price or fund is less volatile than the market.That said, high-beta stocks seek to capitalize on consistent 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 the rivals. However, these exhibit a higher level of volatility.Given this bullishness, investors could find the following ETFs and stocks as intriguing options:ETF PicksWe have chosen ETFs that are not confined to a specific sector or industry but offer exposure to the broader stock market.Pacer Lunt Large Cap Alternator ETF ALTLThis ETF is a strategy-driven, large-cap ETF that seeks to track the investment returns of an index that alternates exposure between low-volatility and high-beta stocks in the S&P 500 Index.Zacks Rank: NABeta: 2.87AUM: $54.7 millionExpense Ratio: 0.60%LeaderShares Equity Skew ETF SQEWThis is also an actively managed ETF that employs a contrarian strategy seeking to buy underperforming asset classes and/or factors and sell outperforming asset classes and/or factors based on quantitative research.Zacks Rank: NABeta: 2.17AUM: $69.4 millionExpense Ratio: 0.75%Invesco S&P SmallCap 600 Pure Value ETF RZVThis fund provides pure exposure to the small-cap stock that exhibit strong value characteristics by tracking the S&P SmallCap 600 Pure Value Index (read: Red-Hot Small-Cap ETFs to Bet on as Biden Takes Over Office).Zacks Rank: #3 (Hold)Beta: 1.74AUM: $180 millionExpense Ratio: 0.35%Invesco S&P MidCap 400 Pure Value ETF RFVThis product offers exposure to the mid-cap stocks that exhibit strong value characteristics by tracking the S&P Midcap 400 Pure Value Index.Zacks Rank: #3Beta: 1.67AUM: $80.1 millionExpense Ratio: 0.35%Invesco S&P 500 High Beta ETF SPHBThis fund offers exposure to stocks with the highest sensitivity to market movements, or beta over the past 12 months.
