Korea's KOSPI just had its worst day since 2024, down 7.2% in a single session. Samsung and SK Hynix got crushed, circuit breakers were triggered, and foreign investors dumped over $3 billion in Korean equities. We break down exactly why it happened and who is winning right now.

To understand today's selloff, you have to trace the full chain. US tariffs on China led to Beijing retaliating with refined rare earth export restrictions. The US captured Maduro in Venezuela. And now a full-scale war with Iran is threatening the Strait of Hormuz and spiking energy costs for the most energy-dependent semiconductor fabs on the planet. These are not separate headlines. They are one connected geopolitical realignment playing out in real time, and the FRDM ETF is quietly positioned perfectly for this moment.

We also cover CrowdStrike's latest earnings, what China's rare earth restrictions mean for defense and semiconductor supply chains, and why waste management companies deserve a serious look in this environment.

This is the macro-to-portfolio analysis you won't find on CNBC.

First, Berkshire Hathaway. We break down their Q4 2025 results — operating earnings fell nearly 30% year over year to $10.2 billion, dragged down by a 54% collapse in insurance underwriting profits. We put that number in context, explain why it looks worse than it actually is, and walk through how Berkshire actually makes its money: the key revenue segments powering the conglomerate, from the insurance float engine and GEICO to BNSF Railroad, Berkshire Hathaway Energy, and its vast manufacturing and services businesses. We also touch on the Greg Abel era beginning and what investors should watch next.

Then we turn to MongoDB. MDB beat on both earnings and revenue — $695M in quarterly revenue, up 27% year over year, with Atlas cloud revenue growing 29% and crossing a $2 billion run rate for the first time. So why did the stock crash 24% after hours? We explain exactly what spooked the market — and whether this selloff is a buying opportunity or a warning sign.

This is Rigatoni Capital — long-term thinking for serious investors.

On the first trading day since the outbreak of the US-Iran war, we break down how defense stocks are responding and what long-term investors should be watching. Then we shift to earnings season — what's coming this week and what matters. We close with a look at Berkshire Hathaway and American Express weakness, and what that signals about consumer and financial sector sentiment. All of it through the Rigatoni Capital lens: macro, geopolitics, and where capital flows next.

In this episode of Rigatoni Capital, I break down market sentiment coming out of last week's earnings and dive deep into U.S. defense manufacturers — including whether the ITA ETF makes more sense than picking individual names like Lockheed Martin, Raytheon, and Northrop Grumman for a long-term portfolio.

I also preview Broadcom's earnings report this Wednesday, cover the broader semiconductor landscape, and walk through my 2026 watchlist for buy and hold investors.

This show is built for long-term investors, not traders. No stock picks — just a framework for thinking about portfolio management and positioning for the years ahead.

With U.S. and Israeli forces launching joint strikes on Iran this morning under Operation Epic Fury and Operation Shield of Judah, we break down what's happening in real time and what it means for your portfolio. We walk through the defense manufacturer thesis — LMT, RTX, NOC, LHX — and why a permanent allocation to this sector acts as geopolitical insurance rather than a tactical trade. We cover the ITA ETF, why owning individual names gives you cleaner exposure than the index, and how today's events validate the case for always having defense in your book. We also touch on oil, Palantir's unique positioning as a defense-adjacent tech name, and the key market levels to watch when equities reopen Monday.

This episode discussed my personal portfolio including top positions in Palantir, AppLovin, NVIDIA, Caterpillar, Lockheed Martin, and the XLU utilities ETF. I break down why I believe Palantir and AppLovin are structurally different from traditional SaaS companies and why they are built to win in the AI era rather than be disrupted by it. This episode touched on HALO stocks — Heavy Assets, Low Obsolescence — and why they belong in a diversified long term portfolio alongside high growth tech.

Finally I walk through how I use Claude as my primary research partner — from running the Rigatoni Market Intelligence Briefing every morning which scans dozens of financial sources simultaneously and produces an institutional quality briefing across all asset classes, to running deep dive research reports on individual companies. This is the tool that levels the playing field for retail investors who also have a full time job and a life.
