Speaker states his firm has put on "long dated out of the money put spreads" on HYG and LQD to play the thesis that AI-driven job displacement will cause a credit market cataclysm. He believes AI will cause profound job losses in the knowledge economy, which will lead to 401(k) outflows from passive equity funds. This, combined with passive market mechanics, will crush equities and spill over into credit, causing spreads to widen sharply. Credit ETF underlying liquidity may dry up, exacerbating the downside. The trade structure (put spreads) is designed to avoid shorting and cap downside risk while positioning for a significant widening of credit spreads and a decline in these ETF prices. The timing of the AI job displacement is uncertain and could be years away; geopolitical events (like the Iran war) can distract the market and delay the thesis from being priced in.

Block explicitly states his fund has put spreads on HYG and LQD ETFs to play the thesis that credit spreads will widen. He believes AI-driven job displacement will cause a severe economic/market crisis. This will lead to outflows from passive funds, reversing the flow-driven market multiples and causing credit spreads to widen significantly. SHORT via put spreads because the anticipated crisis will crush the value of corporate debt ETFs. He prefers this over shorting equities due to cheaper volatility and a potential liquidity mismatch during a crisis that could exaggerate ETF downside. The AI job displacement thesis is wrong or its market impact is significantly delayed beyond the option expiry.

Block believes AI will cause massive job losses and a GFC-level market fallout. He cites Mike Green's theory that passive flows have created unsustainable multiples that will violently reverse. A crisis triggered by AI fears or actual economic damage would cause redemptions from passive index funds (like those tracking the S&P 500). The flow reversal would act as a massive, indiscriminate selling force with few active buyers to absorb it, leading to a broad market crash. AVOID. While he expects a major downturn, he advises *against* shorting the "Mag 7" or index directly due to timing risk. His own protection is via option spreads, not outright short positions. The directive is to avoid being long the broad market. The passive flow dynamic remains stable, or a different catalyst (e.g., government intervention) prevents the violent deleveraging.

When asked if one should short the "Mag 7" to protect against his AI thesis, Block's direct answer was "No." He believes "a lot can happen between now and when this materializes." The Mag 7 are major index components and would suffer in a broad sell-off, but the timing and path are too uncertain to warrant a direct short. AVOID initiating a short position. The risk of being early or wrong on timing outweighs the potential benefit. His preferred method of playing the broader risk is through option spreads on credit ETFs. The AI crisis occurs sooner than expected, making avoiding a short position a missed opportunity.
