Public company stocks can swing wildly when Donald Trump tweets about them, and Wall Street analysts are increasingly paying attention to how social-media chatter interacts with the market.

One firm that helps Wall Street track the buzz on social networks is LikeFolio, which CNBC reported has had some success spotting turnarounds of companies like Chipotle and Under Armour.

Now LikeFolio is bringing some of that insight to everyone by releasing an app, with partner TD Ameritrade, that lets you track when market-moving celebrities tweet about public companies.

They aren’t the first to have this idea. In January, Trigger, a free app that lets you track custom financial signals, released a feature which alerted you when Trump tweeted about one of your stocks. But LikeFolio is taking that one step further and letting you follow various influencers, or sets of them. Unfortunately, some are locked unless you are a TD Ameritrade customers. But the app itself is free.

Here is how it works:

When you first log in (through either email or Twitter), you need to subscribe to a channel.

Some of them are locked unless you are a TD Ameritrade customer.

But others everyone can follow, like Donald Trump ...

... or Sharks, which includes the whole 'Shark Tank' gang ...

... or even Warren Buffett.

Once you subscribe, you'll get notified when they tweet about a company. Within minutes, I got a notification that Donald Trump was tweeting about Aetna (AET).

I could then follow the notification to the feed and see what the tweet was.
