There are many advantages to owing exchange-traded funds (ETFs) in an investment portfolio. ETFs provide diversification, allowing investors to own the entire stock market or stocks of companies that are focused on specific sectors of the economy or market. Some ETFs track the price movements of dozen of stocks, while others track hundreds of equities, and some track only one asset class at a time. For investors who are nervous about betting on a single stock, or who want diversification and the margin of safety it provides, ETFs are indeed a great choice. Typically, ETFs are passive investment vehicles and they charge lower fees than competing mutual funds, which are actively controlled by a fund manager who picks stocks. The lower fees can make a big difference to investors over the long-term. Here is riding the bull: three ETFs to capitalize on the ongoing market surge.

Nearly two months after their launch in the U.S., BlackRock (NYSE:BLK) leads the new crop of nearly a dozen spot Bitcoin (BTC-USD) exchange-traded funds (ETFs) with its iShares Bitcoin ETF (NASDAQ:IBIT). The BlackRock ETF, which tracks the price movements of BTC, has attracted $10 billion of investor capital in less than two months, making it the fastest fund ever to reach that milestone.

Moreover, with Bitcoin’s price now at an all-time high of over $72,000, money continues to flow into the IBIT ETF. Since its launch in mid-January, the fund has gained 55%, marking a big increase in a short period of time. With many analysts and market observers forecasting that Bitcoin’s price will more than double from current levels and reach $150,000 by year’s end, there’s plenty of reason to remain bullish on this ETF.
