Investors should buy the dips in the stock market as the S&P 500 looks resilient in the face of higher interest rates, strategist says

• Investors should buy stocks during weak periods in the S&P 500, Fundstrat's head of global technical strategy said. 
• Mark Newton said stocks have largely been resilient in the face of climbing bond yields.
• The strategist sees the S&P 500 reaching 4,250 in March, a gain of about 3% from Tuesday's close. 

Investors should take advantage of pullbacks in the S&P 500 and buy stocks as seasonality and other factors are in place to drive the broad equity index back up to an area not seen in six months, according to Fundstrat's lead technical strategist.
