Wall Street has enjoyed a huge rally this year, with the S&P 500 logging in gains of more than 25% so far. In fact, the benchmark is on track to register its best performance since 2013 and the third-strongest annual gain since the start of the century.

The bullish trends will likely continue heading into the New Year powered by the Fed’s accommodative interest-rate policy and a resilient domestic economy. Additionally, the prospect of a U.S.-China trade deal will further drive stocks higher. As such, most analysts have provided a strong outlook for the S&P 500 in 2020 (read: 10 Best Performing Stocks of S&P 500 ETF).

Canaccord Genuity equity strategist has provided the most bullish forecast for S&P 500, expecting the index to increase 9.7% to 3,4440 by 2020 end. Sam Stovall, the chief investment strategist at CFRA Research, expects the index to rise 9.5% to 3,435 next year and Credit Suisse expects the S&P 500 to move up by 9.2% to 3,425. J.P. Morgan has set the 2020 price target at 3,400, implying an 8% gain. It expects most of the upside to be realized before the U.S. presidential election in November 2020. Per the analyst, the election is generally good for stocks with the S&P 500 rising 12%, on average, through the prior year with a hit rate of 90%.

Stovall also points out that the S&P 500 has advanced in 78% of presidential election years since World War II, recording an average return of 6.8%. During the six years in which a first-term Republican president was seeking re-election, the S&P 500 was up 100% of the time, with a gain of 6.6%, on average.

How to Tap?

Against such a bullish backdrop, investors seeking to participate in the S&P 500 rally could consider ETFs that replicate the index. While these funds look similar in terms of the holdings’ break up, with Apple (AAPL - Free Report) and Microsoft (MSFT - Free Report) taking the top two spots, there are a few key differences between them that are highlighted below.
