if (!isNaN(MarketCap)) {
MarketCapTotal += parseInt(MarketCap);
}

Also, your parseInt() function really should specify the radix you want.
You can get some unforseen issues if you don't. So,

MarketCapTotal += parseInt(MarketCap);

would become

MarketCapTotal += parseInt(MarketCap, 10);

Hope that helps.
