Stock market: should you buy or sell?

The stock market has soared despite no news to support the new highs. Is it time to sell or to short? Or to buy?

Yes, it’s likely you need to add one or even a few data scientists to the team, but not as your first step into the wide, wide world of Big Data. Give me a few minutes and hopefully you’ll see it my…
