The news of the founding family considering taking Nordstrom private has led to a significant spike in the stock price, reflecting investor optimism about the potential for a buyout at a premium. The involvement of reputable financial advisors like Morgan Stanley and Centerview Partners further adds credibility to the potential deal, although it's noted that there's no certainty a deal will occur. The stock's performance above its 200-day moving average prior to the news suggests a bullish sentiment that could be bolstered by these developments.
