Instead of trying to scrape the website which uses Java script I decided on a different approach. The following code opens a CNBC Dow 30 web page, uses Ctrl-A and Ctrl-C to copy the page into clipborad. This is imported into Matlab. Its not fancy, but it works! Make sure you have already run Chrome (or whatever browser you use) as it speeds up the code response time. Data will be in A.
h = actxserver('WScript.Shell');
h.Run('chrome'); %Invokes chrome.exe
pause(5); %Waits for the application to load.
h.AppActivate('chrome'); %Brings chrome to focus
h.SendKeys('https://www.cnbc.com/dow-30/~'); %send web address
pause(5);
h.SendKeys('^a'); % highlight file
pause(2)
h.SendKeys('^c'); % copy file
pause(3)
A = importdata('-pastespecial'); %import formatted data
pause(3)
h.SendKeys('%{F4}'); %close chrome
