Thanks to vaccine optimism coupled with easy money policies, the U.S. stock market is enjoying a boom. The rally has been broad-based with the major indices hitting a series of fresh highs lately.

With only seven trading days left this year, the rally seems to be getting stronger given the so-called Santa Claus rally. A Santa Claus rally refers to the increase in stock prices in the final week of the calendar year (i.e. between Christmas and New Year’s Day) that extends into the first two days of the New Year. According to the Stock Trader’s Almanac, the S&P 500 has gained an average 1.3% during the seven-trading day session since 1969.

Santa Arrives With Bag Full of Gifts!

Coronavirus immunizations have already started in America with Pfizer (PFE Quick QuotePFE - Free Report) shots and more vaccines are on the way. Moderna (MRNA Quick QuoteMRNA - Free Report) , last week, received the FDA authorization for emergency use against COVID-19 in individuals 18 years of age or older. A vaccine will end the pandemic crisis and set the stage for a speedy recovery, thereby boosting demand for several types of products and services in the economy (read: 5 Small-Cap ETFs Set to Explode on COVID-19 Vaccines).

Increased optimism on further fiscal stimulus supports the Santa rally. The House and Senate passed the new coronavirus relief package worth $900 billion. This includes round of $600 stimulus checks to Americans, $300 per week in augmented federal unemployment insurance for unemployed individuals, more than $300 billion in aid for small businesses including through the Paycheck Protection Program, and tens of billions of dollars across other provisions including rental assistance, vaccine distribution funds and broadband support.

Further, the Fed has pledged to hold rates near zero and will continue the asset purchase program at the current rate until “substantial further progress” has been made toward reaching maximum employment and healthy inflation. The lower rates will continue to drive stock prices up.

Although good tidings have already started flowing in, year-end seasonal factors such as holiday optimism, tax-related affairs, investment of Christmas bonuses, mutual fund manager window dressing, and the “January effect” will continue to push stocks higher (read: 6 Secret Santa ETFs to Add Cheer to Your Portfolio).

While most of the ETFs will receive a nice boost, we have highlighted those that are expected to outperform in the seven-day period and are intriguing choices for a short spell. Notably, high-beta and high-momentum products are expected to lead the market in the weeks ahead. This is because high-beta funds experience larger gains than the broader market counterparts in a bullish market. Meanwhile, momentum investing looks to capture profits from buying hot stocks, which have shown an uptrend over a few weeks or a few months.
