The reasons Tesla Inc. climbed so far and is now stumbling are one and the same. The auto pioneer relies on investor confidence the way its cars rely on electricity. The stock closed at $190.63 Friday, good for a decline of 42% this year, at a time when technology investors have mainly been upbeat. The company has shed some $30 billion in market value since last summer.
