Now more than ever is the time to revisit tech stock strategy.

After a 2017 marked by relatively smooth sailing in the stock market, this year has so far rendered investors far more befuddled than last. Volatility has returned to Wall Street and with it come a litany of smart, money-making investing strategies - plus plenty to avoid.

Among the most closely-watched stocks so far this year have been richly valued tech stocks. Are they still safe bets for growth? How might regulation change the way investors look at tech? Will Inc. (AMZN) be able to continue its quest for world domination? And where do cryptocurrencies fit into the picture?

The answers to these hot tech-trade questions and more will come on May 5 when TheStreet's founder and Action Alerts PLUS portfolio manager Jim Cramer hosts a conference: 'How to Diversify Your Portfolio: A Boot Camp for Investors.'

Held in New York City, the all-day event will help you gain the tools to successfully navigate changing markets. With the help of top experts, the conference will cover topics such as long-term wealth building, trading the market, futures and alternative investments (blockchain, gold, cannabis and more).

And in a special segment, Jim Cramer will sit down for an exclusive conversation with PayPal Holdings Inc. (PYPL) Chief Executive Dan Schulman in which the two will discuss the future of technology and how PayPal plans to make the most of an ever-changing landscape. With PayPal's stock up about 80% in the last year, Schulman will undoubtedly be able to offer some color on what makes a smart tech investment.

Now more than ever before is the time to revisit one's strategy to investing in tech stocks. The sector had a white-hot 2017 as the space enjoyed broad-based, large-scale gains. While tech remains a key growth play in 2018, the outlook is evolving.

There's Facebook Inc. (FB) , which is still attempting to weather the Cambridge Analytica scandal. In the wake of the data breach, shares fell sharply. But soon after, as CEO Mark Zuckerberg testified on Capitol Hill, the stock rallied considerably. What's the best way to play Facebook with regulation out of Washington looming over Silicon Valley?

And speaking of Washington, will President Donald Trump be able to rein in growth at Amazon? The commander in chief has been candid in his detest of Amazon and its CEO Jeff Bezos. Can the company avoid the ire of the White House for long, or forever?

There's also Netflix Inc. (NFLX) , which continues to stun Wall Street. The streaming company just reported strong first-quarter earnings with stellar subscription growth. Is the subscription model the new way to go, and how might other firms capitalize?

Don't forget about Apple Inc. (AAPL) . The company's stock turned negative for the year on Monday, April 23, in a monumental trend reversal. Traders have become concerned about Apple product demand, plus the ever-changing chipmaker business on which the company relies.

All in all, tech has plenty of room for growth and plenty of money to be made. But what worked last year isn't guaranteed today. If you want to stay abreast of what will win and what will lose, you don't want to miss TheStreet's May 5 investing boot camp.
