| Dear readers, Welcome to this week's edition of Wall Street Insider. It was great to meet so many of our readers on Monday at our IGNITION: Transforming Finance event at the New York Stock Exchange. We had top tech leaders from firms such as Goldman Sachs, JPMorgan, Morgan Stanley, Citi, BNY Mellon, and Barclays chat about a wide variety of topics, including the threat posed by Silicon Valley to big banks, how to deal with evolving customer expectations around digital, and the cultural challenge of driving innovation in huge organizations. You can check out all of our coverage here, including exclusive stories and video. We'll have more finance events in the future for Prime readers, so stay tuned. If you have any ideas for live events you'd like to see (or feedback from our Transforming Finance event), please don't hesitate to email me at [email protected]. We also had a big series that rolled out this week, which many of you hopefully have seen, focused on the future of big data on Wall Street. Basically, there are massive amounts of "digital exhaust" being produced every day by everything from Instagram to Amazon. This information, if harnessed correctly using technology, can be incredibly valuable. It's creating a data gold rush, with companies expected to spend nearly $190 billion globally this year on software and services to analyze any sort of information that could give them an edge over their competitors. The finance industry — from hedge funds and asset managers to large banks — is at the forefront of this trend. You can read all of our stories here. Please say hello to our new fellow Alex Nicoll who will be focusing his reporting on the wild world of real estate! And good luck to all of our readers taking the CFA!

Hedge funds and private-equity firms are no longer staying in their lanes and increasingly jumping between public and private markets. The convergence of hedge funds and private equity has led to a fight for talent as both sides try to pitch to prospective employees and investors that they are all-encompassing alternative-asset managers. It comes as the starting pool for talent in finance continues to dwindle and Silicon Valley siphons Wall Street professionals away.

More than 20 executive directors in the bank's Model Risk Governance & Review Group were culled this month, according to people familiar with the matter. It wasn't immediately clear whether the cuts extended to other levels of seniority, or whether more personnel changes in the division would follow. READ MORE>> 'Alexa, what ETF should I buy?' Asset managers like BlackRock and Invesco are testing out voice assistants — but some are sounding the alarm on privacy concerns With just a few spoken words, you can schedule doctors' appointments on Alexa, order groceries on Google Home, and ask Siri for flight updates. Soon people will be able to interact just as easily with the companies that manage their investment and retirement accounts. Big asset managers such as BlackRock, Invesco, State Street, T. Rowe Price, and JPMorgan are preparing to roll out tools on platforms like Alexa and Siri as soon as next year, top digital and marketing executives told Business Insider. They're planning to start with simple search-related tasks for voice assistants, like asking Siri about account balances or answering specific market questions, such as how US futures are trading. It's unclear how much investors will use these programs, and some advisers are worried about privacy and encouraging short-term behavior.

Such growth had been tough to come by in recent years as the industry reckoned with a generational shift to passive investing.
