什么是公司β系数?公司β系数与市场风险系数有何区别?

答案

参考答案:

公司β系数是公司特征曲线的斜率,公司特征曲线是以项目的收益为纵坐标,以企业全部经营收益为横坐标所作的回归曲线。

而市场风险系数是指β贝塔系数,贝塔系数衡量股票收益相对于业绩评价基准收益的总体波动性,是一个相对指标。β越高,意味着股票相对于业绩评价基准的波动性越大。β大于1,则股票的波动性大于业绩评价基准的波动性。反之亦然。

Mother-of-three Carmen Blake called her midwife(助产师)to ask for an ambulance when she went into labor unexpectedly with her fourth child.

But the 27-year-old claims she was refused an ambulance and told to walk the 100m from her house in Leicester to the city’s nearby Royal Infirmary(医院).

Her daughter Mariah was delivered on a pavement outside the hospital by a passer-by, just before ambulance crews arrived.

Ms Blake said she started going into labor at about 7:15 am on Sunday, August 2. She said, “I phoned up the Royal Infirmary, it’s just across the road.

“I went into the bath and realized she was gong to come quickly. I didn’t think I’d be able to make it out of the bath, so I phoned the maternity(妇产科的) ward back and told them to get an ambulance out.”

They said they were not sending an ambulance and told me I had had nine months to sort out a lift.

Experienced mother MS Blake today said she knew she had to get herself out of the bath and try to get to the hospital.

Eventually MS Blake and her friends enlisted the help of a physiotherapist(理疗师) who happened to be passing on her way to work. She dialed 999 and helped deliver baby Mariah while waiting for emergency services.

Ms Blake said despite the happy ending she was upset she was told to make her own way to the hospital as, being an experienced mum, she knew she did not have the time.

Today a government spokeswoman said, “We are disappointed that Ms Blake was not happy with the advice and care she received and will of course investigate any complaint. We are pleased that both Ms Blake and her daughter are well and healthy.”
