Traders are awaiting the Fed's meeting results. This is why the trading activity is low. Judging by the premarket stock trading, some shares are facing pressure ahead of the meeting. Let's have a look at the most volatile ones.

Adobe shares declined significantly by more than 3.7% in the premarket despite a positive quarterly earnings report. The company posted revenue of $ 3.94 billion, surpassing Wall Street's consensus estimate of $3.89 billion. Non-GAAP earnings of $3.11 per share also exceeded economists' estimates of $3.01 per share.

FedEx shares sank even more after the company's quarterly net profit did not meet expectations. The transportation company reported earnings of $4.37 a share, 54 cents below analysts' consensus. As a result, in the premarket, the shares were already trading 6.1% below the closing level of yesterday.

SoFi was among the biggest gainers. SoFi shares jumped by 3.4% after the company launched an application with a purchase rating. At the same time, the company said that in the next 12 months, the shares may grow by more than 60%. "We believe that 'Flywheel,' SoFi's synergistic business model, will continue to drive significant user growth, product adoption, and margin expansion," Jefferies analysts wrote in a note.

Stitch Fix shares saw the sharpest increase of 12.8% in early morning trading after reporting surprisingly high earnings results in the fiscal fourth quarter. The online shopping and styling service reported earnings of 19 cents per share versus an expected loss of 13 cents per share. Stitch Fix also topped revenue projections, reporting 18% year-over-year growth in the active clients.

The placement of 7 million Class A common shares to finance its acquisition of Apple Leisure Group negatively affected the shares of Hyatt Hotels. Their price fell by 1.2% in the premarket. Disney shares rose by 0.9% after a statement of Credit Suisse. The agency said that the selloff in Disney that took place yesterday was an overreaction and the stock could rebound more than 27%.

Shares of entertainment giant lose more than 4% on Tuesday after CEO Bob Chapek warned of problems with subscription video streaming growth in the fourth quarter and projected lower-than-expected fourth-quarter subscriber growth.

As mentioned above, investors have now turned their focus on to the Fed meeting, which will end today. Immediately after the announcement of the decision on the interest rate, Fed Chairman Jerome Powell will deliver a speech. The central bank faces a difficult task to calm down markets and at the same time prepare investors for the gradual tapering of the QE program. The stock market sentiment will depend on the decision of the Fed on QE. The main US stock indices may sink even more after the meeting. If Powell's speech is neutral, the US stock market is likely to recover in the next few weeks, especially since current prices are quite attractive for traders.

As the S&P500, tomorrow, it may reach the level of 4,231. However, this scenario may occur if the index breaks though the 4,300 level and the Fed announces tapering. The stock market may get back on path to recover only after the index rises above the 4,425 level and then to 4,475 and 4,525.
