1 引言¶

研究目的:
本文参考广发证券《基于日内高频数据的短周期选股因子研究-高频数据因子研究系列一》,对研报构造的因子做了实现,并复现了里面的结果,做出了分析。其中用个股日内高频数据构造选股因子,低频调仓的思路是一个很好的方向。

研究内容:
基于个股日内高频数据,构建了已实现波动(Realized Volatility) 𝑅𝑉𝑜𝑙,已实现偏度(Realized Skewness)𝑅𝑆𝑘𝑒𝑤、已实现峰度(Realized Kurtosis)𝑅𝐾𝑢𝑟𝑡因子指标,考察这三个因子在回测区间内对个股收益率 的区别度。

研究结论:
在三个因子中偏度$RSkew$因子最有效,分组区分度高,比较稳定,收益最高。

2 因子构建¶

因子构建过程摘自研报,具体因子指标构建如下:

  1. 对于每个个股在交易日t,首先计算个股在特定分钟频率下第i个的收益率 $r_{t,i}$, $r_{t,i}$ = $p_{t,i}$ − $p_{t,i-1}$,其中$p_{t,i}$表示在交易日t,个股在第i个特定分钟频率下的对数价格,$p_{t,i-1}$表示在交易日t,个股在第i−1个特定分钟频率下的对数价格。

  2. 对于每个个股,根据𝑟𝑡,𝑖分别计算个股在交易日t下的已实现方差(Realized Variance) $RDVar_t$、已实现偏度(Realized Skewness) $RDSkew_t$,已实现峰度(Realized kurtosis) $RDKurt_t$。其中:

$$RDVar_t = \sum\limits_{ i=1}^{n}r_{t,i}^2$$

$$RDSkew_t = \frac {\sqrt N\sum\limits_{ i=1}^{n}r_{t,i}^3}{RDVar_t^{3/2}}$$

$$RDKurt_t = \frac {N \sum\limits_{ i=1}^{n}r_{t,i}^4}{RDVar_t^2}$$

其中N表示个股在交易日t中特定频率的分钟级别数据个数,如在1分钟行情级别下,数据个数N为60*4=240;在5分钟行情级别下,数据个数N为240/5=48。

  1. 对于每个个股在交易日t计算累计已实现波动(Realized Volatility)$RVol_t$, 已实现偏度(Realized Skewness)$RSkew_t$、已实现峰度(Realized Kurtosis) $RKurt_t$ ,其中: $$RVol_t = \left(\frac{242}{n} {\sum\limits_{ i=0}^{n}}RDVar_{t-i}\right)^{1/2}$$

$$RSkew_t = \frac{1}{n}{\sum\limits_{ i=0}^{n}}RDSkew_{t-i}$$

$$RKurt_t = \frac{1}{n}{\sum\limits_{ i=0}^{n}}RDKurt_{t-i}$$

  1. 在每期调仓日截面上,按照上述公式计算每个个股的已实现波动(Realized Volatility)$RVol_t$,已实现偏度(Realized Skewness)$RSkew_t$、已实现峰度(Realized Kurtosis)$RKurt_t$指标,针对每个由高频数据计算得到的因子指标在历史上的分档组合表现,试图寻找出相对有效的因子指标。

3 构造因子数据¶

计算因子值的过程比较慢,大概耗时1小时左右。如果直接下载我构造好的数据文件(factor_dict.pkl)上传到研究里可以跳过这一步,直接到因子特征展示开始执行。

以下开始计算因子值:

import pandas as pd
import numpy as np
from jqdata import *
import math
from pandas import *
from datetime import date, timedelta

N = 48
n = 5
# 获取某个交易日的因子值
def get_one_trade_day_data(cache = {}, stocks = None, trade_date = None):
#     print(trade_date)

    # 后面需要在交易日t计算累计已实现波动等数据,需要获取交易日t到交易日t-n之间的交易日
    trade_days = get_trade_days(start_date=None, end_date=trade_date, count=n)

    # dataframe的index,为股票code
    factor_df_index = []

    # 计算得到的因子数值
    factor_df_data = []
    for security in stocks:
#         print(security)

        # 获取收盘价、是否停牌。
        price_info = get_price(security, start_date=None, end_date=trade_date, frequency='daily',
                               fields=['paused', 'close'], skip_paused=False, fq='pre',
                               count=n)

        # 交易日t 当日的收盘价
        t_close = price_info.iloc[-1]['close']

        # 过滤停牌数据(如果过去n日某天有停牌,后面计算偏度时的分母是0会报除0异常)
        # 如果有paused为1的数据,会被drop掉 则长度是0
        if len(price_info.T.replace(1.0, np.nan).dropna().index.values.tolist()) == 0:
#             print("含有停牌数据,continue")
            continue

        # 前n个交易日已实现方差之和
        sum_rd_var = 0.0

        # 前n个交易日已实现偏度之和
        sum_rd_skew = 0.0

        # 前n个交易日已实现峰度之和
        sum_rd_kurt = 0.0

        # 遍历t-n交易日 到 t交易日
        for trade_day in trade_days:
            # 如果重复调用get_bars实在是太慢了,这里缓存一下数据
            if trade_day in cache.keys() and security in cache[trade_day].keys():
                bars = cache[trade_day][security]
            else:
                # 这里要获取交易日当天的数据 所以end_dt要+1
                # 研报中N为48,对应的频率为5分钟(一个交易日有60*4=240分钟,240/48 = 5)
                bars = get_bars(security, N, unit='5m',
                                fields=['date', 'open', 'high', 'low', 'close'],
                                include_now=False, end_dt=trade_day + timedelta(days=1), fq_ref_date=None)
                if trade_day not in cache.keys():
                    cache[trade_day] = {}
                cache[trade_day][security] = bars

                # 个股在特定分钟频率下第i个的收益率
                rt = pi - pi_1

                sum_rt2 += math.pow(rt, 2)

            sum_rd_var += rd_var
            sum_rd_skew += rd_skew
            sum_rd_kurt += rd_kurt

        # 累计已实现波动
        r_vol = math.sqrt((242.0 / n) * sum_rd_var)

        # 已实现偏度
        r_skew = (1.0 / n) * sum_rd_skew

        # 已实现峰度
        r_kurt = (1.0 / n) * sum_rd_kurt

        # 数据填充
        factor_df_index.append(security)

4 因子特征展示¶

通过上文中的代码,已经获取到了中证500成分股2013-2019的因子数据。

以下分别从因子频率分布、因子百分位走势2个维度展示因子特征。

1 频率分布¶

import pickle

import matplotlib.pyplot as plt
import numpy as np

# 读取因子数据文件
pkl_file = open('factor_dict.pkl', 'rb')
factor_dict = pickle.load(pkl_file)
pkl_file.close()

# print(factor_dict)

import matplotlib.dates as mdate
# 设置字体 用来正常显示中文标签
plt.rcParams['font.sans-serif'] = ['Arial Unicode MS']

# 用来正常显示负号
plt.rcParams['axes.unicode_minus'] = False
market_vol = []
market_skew = []
market_kurt = []

for date in factor_dict:
    factor_df = factor_dict[date]
    for i in range(0, len(factor_df)):
        factor = factor_df.iloc[i]
        market_vol.append(factor['r_vol'])
        market_skew.append(factor['r_skew'])
        market_kurt.append(factor['r_kurt'])

"""
绘制直方图
data:必选参数,绘图数据
bins:直方图的长条形数目,可选项,默认为10
density:是否将得到的直方图向量归一化,可选项,默认为0,代表不归一化,显示频数。normed=1,表示归一化,显示频率。
facecolor:长条形的颜色
edgecolor:长条形边框的颜色
alpha:透明度
"""
# 这个颜色是我把研报的图截图用取色器取出来的,为什么画出来还是有色差?
color = "#1F77B4"
plt.hist(market_vol, bins=40, density=0, facecolor=color, edgecolor=None, alpha=1)
# 显示横轴标签
plt.xlabel("区间")
# 显示纵轴标签
plt.ylabel("频数")
# 显示图标题
plt.title("个股波动率分布")
plt.show()

plt.hist(market_skew, bins=40, density=0, facecolor=color, edgecolor=None, alpha=1)
# 显示横轴标签
plt.xlabel("区间")
# 显示纵轴标签
plt.ylabel("频数")
# 显示图标题
plt.title("个股偏度分布")
plt.show()

plt.hist(market_kurt, bins=40, density=0, facecolor=color, edgecolor=None, alpha=1)
# 显示横轴标签
plt.xlabel("区间")
# 显示纵轴标签
plt.ylabel("频数")
# 显示图标题
plt.title("个股峰度分布")
plt.show()

从以上因子分布三图看出,整个A股市场个股的波动率分布整体上呈现右偏分布;个股的偏度分布,整体偏度水平保持在零附近,呈现较为明显厚尾状态;个股的峰度分布与个股波动率水平类似,分布整体上右偏,且样本内个股的峰度水平大部分大于3,呈现厚尾的现象。

和研报中的三个因子分布图情况和结论相同。

2 百分位走势¶

    label_list = ['10', '25', 'median', '75', '90']

    # 这里需要用每天的因子数据分档,计算出5个折线
    y_list = [[], [], [], [], []]

    for date in factor_dict:
        factor_df = factor_dict[date]
        day_factor_values = []
        for i in range(0, len(factor_df)):
            factor = factor_df.iloc[i]
            # 'r_vol', 'r_skew', 'r_kurt'
            day_factor_values.append(factor[factor_name])

        # 把day_factor_values分为5档
        day_factor_values = np.array(day_factor_values)
        day_factor_values.sort()

        # 研报的5个分位数分别是10 25 50 75 90
        q_list = [0.10, 0.25, 0.50, 0.75, 0.90]
        for i in range(0, len(q_list)):
            # 对应分位数位置
            q_index = int(q_list[i] * len(day_factor_values))

            # 对应分位数位置的因子值
            factor_value = day_factor_values[q_index]
            y_list
