Vickers Stock Research, a subsidiary of Argus Research Group, tracks and analyzes insider trading and institutional stock ownership trends. Form 13-Fs, which institutions must file to report their holdings, are due 45 days after the end of calendar quarters, and have now come in from 1Q26. We like to review the 13Fs of major activist investors -- including Carl Icahn, Trian Fund Management, Jana Partners, Starboard Value and ValueAct Holdings, among others -- in order to determine their core holdings and new purchases. Activist investing has evolved in recent years and is now less about generating a short-term return on an underpriced stock and more about achieving long-term returns through an active management/investor partnership. Activists have made progress in the past year, with high-profile investments into blue-chip companies such as Fedex and Union Pacific. Here are some recent new purchases and key holdings of activist investors, as well as other high-profile money managers.

This is one of the busiest weeks of the year on Wall Street. There's a Fed rate meeting, which is also the last meeting with current-but-departing Chairman Jerome Powell. As well, five of the Mag7 are due to report earnings and there's a lot of economic data coming out (including updated on GDP and inflation). Last week, the Dow Jones Industrial Average and the S&P 500 were essentially flat, while the Nasdaq gained 1.5%. Year to date, all three indices are in positive territory. The Dow is up 2%, the S&P 500 is higher by 5%, and the Nasdaq is up 7%. On the earnings calendar, about 850 public companies are reporting this week. Highlights include Verizon on Monday; Visa, Coca-Cola, Novartis, Seagate Technology, Starbucks, and UPS on Tuesday; Alphabet, Microsoft, Amazon, and Meta Platforms on Wednesday; Apple, Eli Lilly, Merck, and Caterpillar on Thursday; and Exxon Mobil and Chevron on Friday. Turning to the economic calendar, the Case-Shiller Home Price Index will be reported on Tuesday; the Federal Reserve rate decision comes on Wednesday (followed by a final press conference hosted by Chairman Powell); and the Personal Consumption Expenditures Index inflation indicator and an update on GDP hit the tape on Thursday. The impact of the war is showing up in economic forecasts. Gas prices have been elevated, but fell eight cents last week and are now at an average of $4.04 per gallon for regular gas. The Atlanta Fed GDPNow forecast is now calling for 1.2% growth in 1Q, down from 3.0% about a month ago. The Cleveland Fed Inflation Nowcast forecast is at 3.6% for CPI in April, up from the 3.3% print in March. Mortgage rates moved lower last week, down seven basis points, with the average 30-year fixed-rate mortgage at 6.23%, according to FreddieMac. For the Federal Open Market Committee (FOMC) meeting this week, odds are at zero for a rate move. President Trump's nominee to be the next Fed chairman, Kevin Warsh, testified before Congress last week as he continues to move through the formal approval process. Of note, the controversial DOJ investigation into Chairman Powell was dropped. His term as Chairman expires on May 15, though he will remain on the committee.
