Gork，就放了结论，前面一堆分析就略了

Conclusion

Berkshire Hathaway’s stock may increase when the stock market is down due to its massive cash reserves ($325–$334 billion), providing stability and buying power; diversified, resilient businesses (e.g., GEICO) ensuring earnings; potential share buybacks supporting the price; its perceived safe haven status amid Buffett’s reputation; and contrarian positioning that signals future opportunities.
