请问这句话怎么翻译比较好？

1. 翻译：

在1999至2002年间，股东见证了他们所持股票股值的缩减，

而此前的乐观主义者也不得不屈服于事实。

====================

  2.  解释：

个人觉得这里as是连词，表示At the same time，同时发生~

眼看股价下跌的同时，乐天派们（也）不得不向现实低头~

要是翻译成表转折的"虽然但是"，

就成了“虽然乐天派屈服于现实，但是股价下跌了”，有点别扭~

1999至2002年间，由于之前的乐观被（严酷的）现实而取代【give way to 给…让路，对…让步，被…代替】，预期股东们眼睁睁看着他们的股份缩水。

在1999年和2002年之间的控股股东看到的价值缩减早乐观让位于现实。
望采纳~~

在1999年和2002年之间，由于早期乐观主义让步于现实，股东们发现了他们所持股票涨缩的价值。

1999到2002年间，虽然早期有乐观估计，但是股东们还是看到他们的股票缩水了，（在这个事实面前），那些早期的乐观派们不得不得向事实低头。
