Despite its ups and downs as a business and as a platform, there is one thing Twitter (TWTR) has always had over other social networks -- its ability to move markets.
From legendary investment gurus to retail investors to hedge fund honchos to influential journalists, most of the world's financial elite are on the platform, giving their opinions on the day's events or actually breaking the news itself which moves markets.
While there are countless people which could be put on this list, TheStreet narrowed it down to 15 people that are a must follow for any investor.
The list is comprised of people and institutions that have killer analysis, quick wit and a personality that can't be matched.
No list should start without TheStreet's own Jim Cramer (@jimcramer).
After working at Goldman Sachs and then founding his own hedge fund, Cramer, with his more than 1 million followers, gives investing advice for all the world to see, trying to help anyone who asks for it.
When he's not tweeting about stocks, Cramer is an avid Philadelphia Eagles fan and has something of a green thumb, talking about his vegetable garden.
Joe Weisenthal is currently the co-host of "What'd You Miss?" on Bloomberg TV and an editor at Bloomberg, but it's his Twitter account that has helped him rise over the years.
TheStalwart, as he's known, has over 130,000 followers and starts every day, waking up way before the birds do and asks "What'd I miss?"
Weisenthal weighs in (a lot) on the day's current events and offers insightful opinions on everything from macroeconomics, to cryptocurrencies, to Chinese food.
Dubbed "the Bond King" by many on Wall Street, DoubleLine CEO Jeffrey Gundlach makes markets move whenever he talks.
Though he's new to Twitter, having just signed up earlier this month, Gundlach has captured the attention of 24,000 followers already -- many who've listened to him talk about Bitcoin, U.S. GDP and even his beloved Buffalo Bills.
The Chairman of Icahn Enterprises, Icahn has made his billions by cleaning up companies and taking big stakes in companies that do (and don't) need his help.
A self-described person who makes his money "studying natural stupidity," Icahn is also an adviser to President Donald Trump to lobby for rule changes, some of which have brought the 81-year old New Yorker scrutiny, according to those on Capitol Hill.
The self-proclaimed "Chairman of the Twitter Federal Reserve," Josh Brown is the CEO of Ritholtz Wealth Management, a member of CNBC's The Halftime Report and a solid follow on Twitter.
His followers -- of which there are now more than 660,000 -- all get Brown's funny and smart takes on the day's events, be they financial related or otherwise.
The former Chairman of the Federal Reserve, Ben Bernanke may not be the most active tweeter on the list, but his 85,000 followers learn something every time he posts.
Now a distinguished fellow in residence at the Brookings Institution, Bernanke posts links to his blog where he often weighs in monetary policy issues around the world, such as the extreme measures that the Bank of Japan is taking or whether the Federal Reserve should shrink its balance sheet soon (hint: he says it shouldn't).
Bespoke Investment Group puts out some incredible and insightful research, be it on the NASDAQ, short ratios on heavily shorted stocks such as Shake Shack (SHAK) or some very funny takes on news events.
Though Bespoke only has 58,000 followers, this group definitely deserves the eyes and ears of every investor.
Unlike most Federal Reserve accounts, the St. Louis Federal Reserve has an active account which is insightful, thought-provoking and occasionally humorous.
It has more than 70,000 followers and weighs in on a lot of important financial issues and helps give investors insight they may not get elsewhere.
Any good investors needs to understand the positives and negatives to a company and one that exemplifies that is Carson Block and his firm, Muddy Waters Research.
With more than 40,000 followers, Muddy Waters sends out updates on its short positions, as well as research and insight into its thinking.
You may think of Mark Cuban as just the fiery owner of the Dallas Mavericks and a star on "Shark Tank," but his 7 million Twitter followers often get much more bang for their buck from the internet billionaire.
Cuban, who has toyed with the idea of a run for President of the United States in 2020, openly weighs in on stock market and single stock valuations, as well as discussing economic ideas.
Aswath Damodaran is a highly-respected valuation expert and professor at NYU.
Mohamed El-Erian may best be known for being the former CEO of global investment manager PIMCO, but he also offers insightful takes on economic news on Twitter as well.
Now a Chief Economic Adviser at Allianz, El-Erian is also the author of two New York Times bestsellers When Markets Collide and The Only Game in Town.
When he's not tweeting about the markets, he also weighs in on a variety of other topics, including his beloved New York Jets.
Few investment banks tweet as often (and as well) as Morgan Stanley does.
Its account has over 400,000 followers and it shares its views, research and appearances by employees.
A political scientist, president of the Eurasia Group and an NYU professor, Ian Bremmer drops knowledge with every tweet to his 270,000 followers.
Bremmer will often weigh in on things going on around the world both in the political space and in markets. He'll occasionally write poetry too and uses a sly, subtle sense of humor to get it done.
Like Morgan Stanley, Goldman Sachs is active on Twitter, tweeting out insight, snippets of research and promoting its employees to its more than 600,000 followers.
