محاسبه بازده ماهیانه سهم قبلا در این پست در خصوص شیوه تغییر تایم فریم داده ها صحبت کردیم. فرض کنید داده های مربوط به یک سهم را به صورت روزانه داریم و می خواهیم بازدهی ماهیانه آن را محاسبه کنیم. یک راه بسیار ساده استفاده از تایع resample است. به کمک این تابع می توانیم قاب زمانی داده ها را متناسب با نیاز خود تغییر دهیم. در مثال این پست، اطلاعات سه سهم دریافت شده و بازدهی ماهیانه آنها محاسبه و رسم می شود. بازه های زمانی متداول در resample عبارتند از: B business day frequency D calendar day frequency W weekly frequency M month end frequency BM business month end frequency MS month start frequency BMS business month start frequency Q quarter end frequency BQ business quarter endfrequency QS quarter start frequency BQS business quarter start frequency A year end frequency BA business year end frequency BAS business year start frequency H hourly frequency T minutely frequency

In general, many financial experts support their clients’ desire to buy cryptocurrency, but they don’t recommend it unless clients express interest. “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college,” says Ian Harvey, a certified financial planner (CFP) in New York City. “Then it wasn’t worth the risk.” The speculative nature of cryptocurrency leads some planners to recommend it for clients’ “side” investments. “Some call it a Vegas account,” says Scott Hammel, a CFP in Dallas. “Let’s keep this away from our real long-term perspective, make sure it doesn’t become too large a portion of your portfolio.” In a very real sense, Bitcoin is like a single stock, and advisors wouldn’t recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if you’re passionate about it. “If it was one stock, you would never allocate any significant portion of your portfolio to it,” Hammel says.
Spiking bond yields driving sharp losses in tech stocks
A spike in interest rates since the start of the year has accelerated a rotation out of high-growth technology stocks and into value stocks poised to benefit from a reopening of the economy. The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year.
A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.
