TheStreet's founder Jim Cramer was on fire Saturday. 

Attendees for TheStreet's Financial Success Strategies teach-in were so excited to see Cramer, they began arriving long before the 8:30 a.m. start time. A couple of college students said they had just taken a train in from Philly (which happens to be Cramer's hometown). Another attendee said he traveled from Singapore to attend a legendary Cramer teach in, which was sponsored by TD Ameritrade (AMTD) and CME Group (CME) .

The event did not disappoint. The moment Cramer walked into the room, it was like watching a rock star make his way through the crowd. The one thing about Jim is that he is completely accessible. He admitted during one of the discussions that he likes to talk stocks with people. "It is just fun to talk stocks," he told the crowd. And he did just that during the early hour meet and greet.

Twitter, apparently, also felt the energy. The #CramerTeachIn hashtag trended all morning.

As he opened the conference, Cramer said, "It's a classic year for stock picking. We're going to see more days like Friday." He went on to say "with markets as crazy as they are, it's a remarkable time to be an investor."

So, WHAT Was Revealed?

Unfortunately for you, we aren't going to reveal everything right now (check back on TheStreet later this week). The reality is that you should have attended to get the must-know insight on the markets that only Cramer and several distinguished market experts in attendance discussed. Just because stock markets are on autopilot doesn't mean you shouldn't actively be trying to better your investing knowledge.

Because believe this to be true: markets don't go up in a straight line. 

But to give you a sampling, Cramer dropped some serious insight into Apple (AAPL) , Starbucks (SBUX) and Facebook (FB) into earnings this coming week. He went onto explain why he likes Nvidia (NVDA) instead of rival AMD (AMD) . Yes, Amazon (AMZN) was a hot topic. And when it wasn't Cramer's time on stage, top names in the world of investing like TD Ameritrade's JJ Kinahan, Marc Chaikin of Chaikin Analytics and TheStreet's markets columnist Stephen Guilfoyle discussed everything from ETFs, futures and markets more broadly. 

Above all else, Cramer took everyone through the exhaustive research process he and his team use to select stocks for members of Action Alerts Plus. To say it's a rigorous process is an understatement -- the service's members should rest easy. In fact, check out several of the ideas Cramer highlighted in the monthly Action Alerts Plus member call (this is a monthly must watch) down below.
